Ryan pitted the GTX670 and GTX570 against each other to show that in terms of gaming performance the GTX670 is a viable upgrade. [H]ard|OCP did something similar, testing the GTX670 and 680 against the HD7970 in a gaming performance showdown. For those who are only interested in gaming performance they've assembled a great breakdown of four popular games at a variety of resolutions and both at stock clocks and the best OC they could manage. The results are clear, for gamers it is NVIDIA with the clear win, with the GTX670 being a better value than the HD7970 and the GTX680 being a better performer.

"Wondering how the GeForce GTX 680 and GeForce GTX 670 compare to the Radeon HD 7970 and Radeon HD 7950 at stock frequencies as well as overclocked? You ask for it and we have done just that. Hold onto your hard earned cash and take note of just how the new GeForce GTX 670 compares with the rest of the competition."

Enthusiasts were offered a bit of hope this morning with news from DigiTimes that more capacity at TSMC will be available for AMD and NVIDIA which would mean more dies being made and hopefully a larger supply of GPUs. Since TSMC seems to have finished playing with their Cortex A9 process, there is a good possibility that the GTX680 and perhaps even the GTX690 will become common enough that the great unwashed actually have a chance to purchase one. We can also hope that it will give NVIDIA a chance to build up stocks of the GTX670 and 610 which are due out at the end of the month and June, respectively. Unfortunately, if a certain site is correct that may not be the case as NVIDIA will be redoing their mask and not be able to take advantage of the extra capacity TSMC could make available for them. Perhaps if this scenario is true AMD will be able to leverage TSMC to flood the market with Southern Island GPUs and hope to win the availability war as the performance crown is firmly on NVIDIA's head in this generation of GPUs.

"AMD and Nvidia, impacted by Taiwan Semiconductor Manufacturing Company's (TSMC's) fully-booked capacity, had rather weak shipment performance in the first quarter; however, as more capacity will be gradually released by TSMC, shortages of 28nm graphics cards are expected to improve in late May, according to sources from graphics card makers."
